Tom Boucher b0c774c2e3 feat(#1416): formalize Resolution convention + agent-skills value envelope (Resolution Provenance P3) (#1425)
Narrows P3 of ADR-1411 (Resolution Provenance, epic #1411) based on an
adversarial fit-analysis that showed a single Resolution<T> envelope adopted
by agent-skills, capability-state, and capability-writer fails the deletion
test: configured/reason are meaningless for capability verbs, and
capability-writer's errors[] (operation-not-applied) cannot fold into
warnings[]. The only genuinely shared seam is warnings: string[].

Changes:

- src/resolution.cts: new pure types+builder leaf — exports Resolution<T>
  {value, configured, reason, warnings}, makeResolution<T>() builder, and
  AgentSkillsValue {block, skills_count}. No other src/ imports.

- src/init.cts: cmdAgentSkills --json IR gains additive value:{block,
  skills_count} field (built via makeResolution). All existing flat fields
  (agent_type, block, skills_count, warnings, configured, reason, source,
  degraded) are retained unchanged for back-compat.

- src/capability-state.cts: doc comment on ResolveCapabilityRuntimeStateResult
  naming it the canonical read-verb envelope. No JSON change.

- src/capability-writer.cts: doc comment on SetCapabilityStateResult naming it
  the canonical mutation-verb result (warnings=advisory, errors=operation-
  not-applied). No JSON change.

- CONTEXT.md: new ### Resolution Convention glossary entry after
  ### Resolution Provenance.

- docs/adr/1411-resolution-provenance.md: P3 narrowing amendment appended.

- tests/resolution.test.cjs: 9 unit tests for makeResolution (new).
- tests/agent-skills.test.cjs: 2 P3 tests for value.block/value.skills_count
  and back-compat of all flat fields.

All 277 tests pass (5 suites). npm run lint clean. All lint checks pass.

/**
* Resolution Convention — canonical shape for config-interpreting read verbs.
*
* Extracted as the anchor for ADR-1411 P3 (Resolution Provenance, #1416).
* Exports the `Resolution<T>` envelope used when a verb reads and interprets
* configuration (e.g. agent-skills). Not used by mutation verbs (see
* capability-writer's `SetCapabilityStateResult` for the mutation shape) or
* plain read verbs (see capability-state's `ResolveCapabilityRuntimeStateResult`).
*
* This is a pure types+builder leaf — no other src/ imports.

// ─── Resolution envelope ──────────────────────────────────────────────────────
/**
* Canonical output envelope for **config-interpreting read verbs**.
*
* - `value` — the resolved domain value (T)
* - `configured` — true when the caller's agent/key was found in config
* - `reason` — machine-readable resolution outcome (e.g. 'resolved',
* 'not_configured', 'configured_empty', 'configured_unresolved')
* - `warnings` — diagnostic messages (empty on nominal path)
*
* The shared contract across all diagnostic shapes is `warnings: string[]`.
* `configured`/`reason` appear only on config-interpreting read verbs;
* mutation verbs add `errors[]` (operation-not-applied) instead.
